  • Publication number: 20240104987
    Abstract: An information processing apparatus includes a registration unit, an acquisition unit, an authentication control unit, and a gate control unit. The registration unit registers first appearance information for registration in association with face information for registration for each registration target person, and updates the first appearance information. The acquisition unit acquires captured image data obtained by imaging an authentication target person. The authentication control unit performs personal authentication of the authentication target person based on a first and a second determination result. The first determination result indicates whether or not face information based on the captured image data corresponds to the face information for registration. The second determination result indicates whether or not first appearance information based on the captured image data corresponds to the first appearance information for registration.
